     Strain Information: 4018/1

Division/Phylum: Heterokontophyta    Class: Oomycota
Eurychasma dicksonii (E.P. Wright) Magnus
CCAP 4018/1
Isolator: Müller (2005)
Origin: Marine; intertidal, Le Caro, Rade de Brest, Brittany, France,
Culture: Medium half strength Provasoli; Bacteria present; sub; 9-15 deg C; lighting 2-10 µE.m-2.s-1 (higher intensities seem to inhibit propagation of Eurychasma)
Other: Orig. desig. Eurychasma 2005 Caro; this is an unialgal host culture - Eurychasma (an oomycete parasite of brown algae) is an obligate biotroph, i.e. it cannot grow outside its host. The host in which this strain is deposited is Ectocarpus sp. CCAP 1310/299, i.e. the original host.; syn. Rhizophydium dicksonii;
